Walter,
I got your pictures and they look pretty good. Haahaa... your butt is catching fire. I can see you are beginning to get a handle on perspective and they all have a lot of personality. I really like the hallway you drew on the “Walter” sketch, with the bad guy walking towards your character. Inking is hard, even with the right tools. I never really got the hang of it. So I don’t draw anime/manga style, which usually has very clean, stylized inking. I’m afraid I can’t help you much there. But I did enjoy sketching with a plain, old bic ball-point pen. You can really force it to give you many different shades and thickness of line if you learn to work with it. I also developed a zen philosophy when I drew with a pen. Everything was permanent so I learned to draw without erasing. I gave in to the fact that nothing is perfect and just kept drawing anyway. You might enjoy that.
You should see if you can get a set of pencils of various hardness’s to help with your shading, which is also coming along really well.
H2 is the hardest/lightest; 6B is the softest/darkest; B is closest to a #2 pencil. You just need to play around with them. You start with the hardest pencils in the set-up to give you a light guide. Start with smooth, light strokes at first so you can always erase something that isn’t working. Then refine the drawing when you know what you want, with the softer pencils which will become darker the softer they are rated.
When you start sketching something original, every instructor will tell you to work light, loose, and fast. I can see you probably like to start with the head and eyes. I used to always start with eyes. I wouldn’t even draw the head. But this leaves many parts of the body/face skewed or out of perspective.
* I want you to try sketching one of your original characters in a very general way. Define the layout of the entire body before you lay down any hard lines so that you can see how the limbs and head are arranged. You don’t need to worry about creating a dynamic pose yet, just make the limbs body and head in proportion. Once the layout “feels” right, then you begin to outline the form define muscle and add clothing on top. People have a very visceral response to what they see; you can feel when something is out of proportion when you look at it, even if you don’t know exactly why. Finding out why takes some time and practice.I also started drawing by referencing comic books I liked and artists I admired. That is a great way to learn. Your Ayane sketch is right on. I recognized her immediately. When I decided to begin creating my own characters I used photos from magazines, and the internet. Thank you, Vogue.
I want to let you in on a little secret. There is no shame in tracing. Even the professionals do it. Granted they usually trace from their own work. But if you look at a picture and wonder, “How did they do that?” tracing can help you figure it out. It also trains your hand to move where you want it to go, and helps you to keep your lines steady. It’s all about training muscle memory. When you have drawn enough, your hand almost draws on its own, and that’s where the real fun starts. I hope you can find something here to help you. Keep at it.
